Body
 I'm trying to encode a video from a byte array buffer and to do so I'm using <code>MPEG4Writer</code> API from native code. I have created my custom <code>MediaSource</code> class to provide the data and I'm wrapping it with <code>OMXCodec</code> to give it to <code>MPEG4Writer</code>: <pre><code>sp<MediaSource> mVideoEncoder = OMXCodec::Create(client.interface(), omxEncMeta, true, mVideoOutSource); mVideoEncoder->start(); </code></pre> <code>mVideoOutSource</code> is my custom <code>MediaSource</code> class, <code>omxEncMeta</code> is the following: <pre><code>int32_t colorFormat = OMX_COLOR_FormatYUV420SemiPlanar; int32_t width = 480; int32_t height = 360; int32_t frameRate = 24; int32_t bitRate = 500 * 1024; int32_t iFrameInterval = 1; sp<MetaData> omxEncMeta = new MetaData; omxEncMeta->setCString(kKeyMIMEType, MEDIA_MIMETYPE_VIDEO_AVC); omxEncMeta->setInt32(kKeyColorFormat, colorFormat); omxEncMeta->setInt32(kKeyWidth, width); omxEncMeta->setInt32(kKeyHeight, height); omxEncMeta->setInt32(kKeyStride, width); omxEncMeta->setInt32(kKeySliceHeight, height); omxEncMeta->setInt32(kKeyFrameRate, frameRate); omxEncMeta->setInt32(kKeySampleRate, frameRate); omxEncMeta->setInt32(kKeyBitRate, bitRate); omxEncMeta->setInt32(kKeyIFramesInterval, iFrameInterval); </code></pre> but when I call <code>start()</code> method it returns the error code <code>UNKNOWN_ERROR</code>. Instead, if I try to give to <code>MPEG4Writer</code> directly my custom <code>MediaSource</code> (without wrapping it with <code>OMXCodec</code> it starts successfully but eventually it will stop recording with the error <code>Missing codec specific data</code> (after about 12 frames), and I think this is because my custom <code>MediaSource</code> provides only informations about the actual frames but nothing about the codec format. I'm sure I'm missing something with <code>OMXCodec</code>, but I can't figure out what... Is there anyone who could provide me with a working example of a custom <code>MediaSource</code> for encoding? Or give me some hints on why this is not working at all? If you need more informations just ask, thanks! EDIT: I'm developing this against API 14 so please don't suggest me to use <code>MediaCodec</code> from API 16 :) EDIT: This is how I'm starting <code>MPEG4Writer</code>: <pre><code>int32_t outputFormat = OUTPUT_FORMAT_MPEG_4; int64_t startTimeUs = systemTime() / 1000; int32_t totalBitRate = bitRate; sp<MetaData> meta = new MetaData; meta->setInt64(kKeyTime, startTimeUs); meta->setInt32(kKeyFileType, outputFormat); meta->setInt32(kKeyBitRate, totalBitRate); sp<MPEG4Writer> mWriter = new MPEG4Writer("/sdcard/encode_manual.mp4"); mWriter->addSource(mVideoEncoder); status_t error = mWriter->start(meta.get()); if (error != OK) { LOGE("Writer NOT started! %x", error); } else { LOGI("Writer started!"); } </code></pre> <hr> This is the output of logcat (<code>adb logcat OMXClient:V OMXCodec:V *:W</code>): <pre><code>W/ResourceType( 370): Skipping entry 0x7f04002f in package table 0 because it is not complex!
